Now this is interesting. We only briefly touched upon Qubes two months ago, and now, the team behind the project have announced a very interesting feature: disposable virtual machines. The idea here is that you can tell your operating system to launch an application in a virtual machine that gets created specifically for opening that application. If you close the application, the VM is destroyed automatically - and this all in under one second.

How does this differ from being a normal OS except with highly restricted interprocess communication? It seems like nothing more than a OS that takes processes partitioning all the way down to the filesystem level.
